testkit: enable infoschema v2 for realtikv test

[tiancaiamao]

What problem does this PR solve?

Issue Number: ref #50959

Problem Summary:

Enable infoschema v2 in realtikv test

What changed and how does it work?

In the past, when I add it to CI I skipped integration, because at that time infoschema v2 can not pass all the tests.
Now I verified that and it is time to add back.

Check List

Tests

• Unit test
• Integration test

All those tests can run under infoschema v2:

Hi @tiancaiamao. Thanks for your PR.

PRs from untrusted users cannot be marked as trusted with /ok-to-test in this repo meaning untrusted PR authors can never trigger tests themselves. Collaborators can still trigger tests on the PR using /test all.

I understand the commands that are listed here.
